PNW Redneck Posted August 12, 2021 Share Posted August 12, 2021 Im looking to trade my ranger for an 02 f250 7.3 6 spd. it has the ZF S6-650 6 Speed 4WD trans. it currently does not have 3rd and 4th. couple questions. A. How hard is it to rebuild these? B. How hard is it to find a good one without ordering a reman online? im heavily considering both options but want a second opinion from people that are far more expierenced with fords than me. im willing to do the work to rebuild it but im also just fine with swapping it.

F350Mike Posted August 12, 2021 Share Posted August 12, 2021 I had a '99 7.3L with a 6 speed and replaced the transmission myself at around 350k mi. This was back in '08 and at that time it wasn't much more to purchase a reman with a 1yr /12k warranty for much more. Now days I couldn't tell you the difference in cost, but over all it wasn't hard to swap out the transmission if you have the proper tools to do it. I also replaced the OE clutch with a South Bend clutch and the throw out bearing. I purchased the reman transmission from Fuller Ford in Cincinnati as I lived in Northern KY at the time.
